No Gyraf, not trolling. Consider the way a rectifier system operates, diodes into a big cap. The cap charges up, then get partially discharged by the load current. The rectifier only conducts when it gets above the cap voltage. In the remaining part of the a.c. cycle where the voltage is higher than what is on the cap, the diode will conduct. So for a very short period of the mains waveform, you have to supply all the power required by the circuit. So if its conducting 10% of the time, and the output current is 500 mA, then the peak current is 5 amps, roughly speaking. What happens is you get a slightly dodgy crimp, and it heats up, oxidising the wire and the terminal. The longer this goes on, the worse it gets. This fault is very common in Eventide 910 and 949 harmonisers and other equipment.
